Hi and welcome.
I'm afraid it's almost impossible to tell what this vase is really like from your picture. I can't make out if there are tiny bubbles in the glass, I can't make out if there's a strange lumpy shape to the base or if there's an angle on the rim or if the vase is round or if it's flattened.
We also need a clear image of the base - and it can often help to know where on earth (literally) you are.
Having said all that, it looks fairly contemporary Polish - there are a lot of vases like this out there!
